Description
- This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2013-107500 filed on May 21, 2013, the entire content of which are incorporated herein by reference.
- The present disclosure relates to a display processing apparatus, a system and a display processing program.
- Many classes are being conducted using mobile terminals, such as a slate terminal, in which a handwriting input is performed by a touch pen or finger, and it is anticipated that these type of classes will be more widely distributed.
- There is a relevant technology in which an image display apparatus constituted by a display unit and a touch panel displays a plurality of corresponding images, along with an image surrounding the plurality of images, when the touch panel corresponding to the plurality of images displayed in the display unit is manipulated.
- Further, there is a technology in which an area surrounded by a circular locus of bright spots of a pointer is displayed in an enlarged scale when an indication position of a pointer is moved by a user into a right direction to surround a portion of a screen-shaped projected image.
- There is also a technology in which a projector generates a zoom image in which a portion of an image is highlighted and an area including the highlighted portion is enlarged, and projects the generated zoom image, based on indication information input by a user.
- See, for example, Japanese Laid-Open Patent Publication No. 2010-113441, Japanese Laid-Open Patent Publication No. 2011-81651, and Japanese Laid-Open Patent Publication No. 2007-219217.
- Following class type may be considered as the class type using the mobile terminal provided with a handwriting input function as described above. For example, an assignment is transmitted from a teacher's terminal to a student's terminal and an opinion regarding the assignment is input to the student's terminal by the student. Also, the student's terminal transmits the input opinion to the teacher's terminal. When the opinions transmitted from the student's terminals are integrated by a teacher, the teacher's terminal may display a plurality of integrated opinions in a matrix shape on an electronic blackboard connected to the teacher's terminal. Also, discussions regarding the opinions may be conducted by students while the plurality of opinions are being displayed on the electronic blackboard. Also, information on dividing the plurality of opinions displayed on the electronic blackboard into an approval group and a disapproval group is input by the teacher in handwriting, and such information is displayed to be overlapped on the plurality of opinions.
- However, it is inconvenient to display the information on dividing opinions into groups to be overlapped on the plurality of opinions in the class type, as described above. For example, when the opinion designated by a teacher is displayed in an enlarged scale in conducting discussion between the students, only a portion displayed within an area of the designated opinion among the information on dividing opinions into groups is displayed. Accordingly, when the opinion designated by the teacher is displayed in an enlarged scale, the information on dividing opinions into groups may not be displayed. Therefore, a teacher or a student is not able to easily identify which group the opinion displayed in an enlarged scale belongs to. Accordingly, there is a problem in that convenience is low in the type of the class as described above in which information on dividing opinions into the groups is displayed by being overlapped on the plurality of opinions. Further, such a problem may similarly occur when displaying the designated data in a case where a symbol such as a figure associated with a plurality of data is displayed to be overlapped on the plurality of data.
- One aspect of the present disclosure intends to enhance the convenience in displaying designated data.
- According to one aspect of the embodiments, there is provided a display processing apparatus including a reception unit configured to receive registration of a symbol by associating the symbol with a plurality of data selected from a group of data when each data included in the group of data is disposed and displayed on a different area among display areas by a display device; and a display control unit configured to control the display device to display the symbol registered by being associated with the plurality of selected data, by associating the symbol with the designated data, when the designated data is included in the plurality of data, in a case where any one data included in the group of data is designated.
- The object and advantages of the disclosure will be realized and attained by the elements and combinations particularly pointed out in the claims. It is to be understood that both the foregoing general descriptions and the following detailed descriptions are exemplary and explanatory, and are not restrictive of the invention, as claimed.
- According to the present disclosure, it is possible to enhance convenience in displaying the designated data.

For example, thestorage unit 14 stores astudent database 14 a, anassignment database 14 b, anassignment reply database 14 c, a coordinatedatabase 14 d and a group-mark database 14 e. Hereinbelow, a database is abbreviated to “DB”. - Various information of students who attend in a class are registered in the
student DB 14 a.FIG. 3 is a view illustrating an exemplary data structure of a student DB. As illustrated in the example ofFIG. 3 , thestudent DB 14 a includes fields for a “student ID”, a “student name” and a “student terminal IP (Internet Protocol) address”. An ID for identifying a student is registered in the “student ID” field in advance. A family name of a student identified by the ID registered in the “student ID” field is registered in the “student name” field in advance. An IP address of thestudent terminal 3 used by the student identified by the ID registered in the “student ID” field is registered in the “student terminal IP address” field. - For example, a first record of the
student DB 14 a illustrated in the example ofFIG. 3 indicates that the family name identified by the ID “1001” is “Tanaka” and the IP address of thestudent terminal 3 used by the student “Tanaka” is “XX.YY.ZZ.A1”. The same rule applies with other records of thestudent DB 14 a. - Information on an assignment presented by a teacher to a student is registered in the
assignment DB 14 b.FIG. 4 is a view illustrating an exemplary data structure of an assignment DB. As illustrated in an example ofFIG. 4 , anassignment DB 14 b includes fields for an “assignment ID”, an “assignment content” and a “reply limitation time”. An ID for identifying an assignment is registered in the “assignment ID” field in advance. The content of assignment identified by the ID registered in the “assignment ID” field are registered in the “assignment content” field in advance. The limitation time indicating a time until a reply is received from a student after an assignment identified by the ID registered in the “assignment ID” field is presented to the student is registered in the “reply limitation time” field in advance. - For example, a first record of the
student DB 14 a illustrated in the example ofFIG. 4 indicates that the content of assignment identified by the ID “0001” is “How do you think about underage abortion?”. Additionally, the first record of thestudent DB 14 a illustrated in the example ofFIG. 4 indicates that a time (limitation time) until a reply is received from a student after an assignment identified by the ID “0001” is presented to the student is “20 minutes”. The same rule applies with other records of thestudent DB 14 b. - The
assignment reply DB 14 c includes a table in which various information on the reply of student about an assignment for each assignment are registered.FIG. 5 is a view illustrating an exemplary data structure of an assignment reply DB. As illustrated in an example ofFIG. 5 , theassignment reply DB 14 c includes a table 14 c_1 in which the reply of student about the assignment for each assignment is registered. The table 14 c_1 includes fields for an “assignment ID”, a “student name”, an “approval/disapproval”, an “opinion content”, a “group ID”, an “opinion display area coordinate”. An ID for identifying an assignment is registered in the “assignment ID” field by thereception unit 15 a to be described below. A family name of a student who replies an opinion about the assignment identified by the ID registered in the “assignment ID” field is registered in the “student name” field by thereception unit 15 a. The content of approval or disapproval replied by the student having a family name registered in the “student name” field is registered in an “approval/disapproval” field by thereception unit 15 a, as an approval or disapproval about the same assignment. The content of opinion replied by the student having a family name registered in the “student name” field is registered in an “opinion content” field by thereception unit 15 a, as an opinion content of the same assignment. - In a case where a plurality of opinions are displayed in a matrix shape to be described below, the coordinates of four corners of an area in which an opinion of the student having a family name registered in the “student name” field is displayed are registered in the “opinion display area coordinate” by the
reception unit 15 a. That is, the coordinate of the left upper position, the coordinate of the left lower position, the coordinate of the right upper position, the coordinate of the right lower position of the area in which the opinion is displayed are registered in the “opinion display area coordinate” field by thereception unit 15 a. - For example, the table 14 c_1 illustrated in an example of
FIG. 5 indicates a table in which the reply of the student about the assignment about “How do you think about underage abortion?” identified by the ID “0001” is registered. Further, a first record of the table 14 c_1 illustrated in the example ofFIG. 5 indicates that the student having the family name of “Tanaka” has an opinion of “disapproval” about “underage abortion” about the assignment of “How do you think about underage abortion?”. Further, the first record of the table 14 c_1 illustrated in the example ofFIG. 5 indicates that the student having the family name of “Tanaka” has replied an opinion content of “i am worried about bringing up child when being unemployed because of the financial aspect” about the assignment of “How do you think about underage abortion?”. Furthermore, the first record of the table 14 c_1 illustrated in the example ofFIG. 5 indicates that the coordinate of the left upper position is (0, 60), the coordinate of the left lower position is (0, 30), the coordinate of the right upper position is (40, 60), and the coordinate of the right lower position is (40, 30) of an area in which an opinion replied by the student having the family name of “Tanaka” is displayed. The same rule applies with other records of the table 14 c_1. - The electronic pen is manipulated on the
electronic blackboard 4 a by the teacher and thus, various information of a mark drawn on theelectronic blackboard 4 a is registered in the coordinateDB 14 d. Further, the touch pen or finger is manipulated on theinput unit 11 by the teacher and thus, various information of a mark drawn on thedisplay unit 12 is registered in the coordinateDB 14 d. That is, various information of a mark input in handwriting by the teacher are registered in the coordinateDB 14 d. Here, the mark is also referred to as a symbol. The mark may be various shapes such as a character, a sign, and a figure. -
FIG. 6 is a view illustrating an exemplary data structure of the coordinate DB. As illustrated in an example ofFIG. 6 , the coordinateDB 14 d includes fields for a “mark ID”, a “start point coordinate”, a “progressed coordinate”, an “end point coordinate” and a “group ID”. - An ID for identifying a mark is registered in the “mark ID” field by the
reception unit 15 a. A start point coordinate of the mark identified by the ID registered in the “mark ID” field is registered in the “start point coordinate” field by thereception unit 15 a to be described below. The coordinates of points between the start point coordinate and the end point coordinate of the mark identified by the ID registered in the in the “mark ID” field are registered in the “progressed coordinate” field by thereception unit 15 a. An end point coordinate of the mark identified by the ID registered in the “mark ID” field is registered in the “end point coordinate” field by thereception unit 15 a. Further, coordinates of points of between the start point coordinate and the end point coordinate of the mark are referred to as progressed coordinates. An ID for identifying a group to which the mark identified by the ID registered in the “mark ID” field belongs is registered in the “group ID” field by thereception unit 15 a. - For example, the first record of the coordinate
DB 14 d illustrated in the example ofFIG. 6 indicates that a coordinate of a start point is (34, 61), the progressed coordinates are (34, 53), (33, 52), (32, 52), (31, 52) . . . , and a coordinate of an end point of a mark identified by the ID “1001” is (39, 63). Further, the first record of the coordinateDB 14 d illustrated in the example ofFIG. 6 indicates that the mark identified by the ID “1001” belongs to a group identified by an ID “1”. - Information on the mark and a group ID to which the mark belongs are registered in the group-
mark DB 14 e by being associated with each other by thereception unit 15 a.FIG. 7A andFIG. 7B are views illustrating exemplary data structures of a group-mark DB. The group-mark DB 14 e illustrated in examples ofFIG. 7A andFIG. 7B includes fields for a “group ID”, a “mark ID”, and a “mark character string”. An ID for identifying the mark is registered in the “mark ID” field by thereception unit 15 a. A character string of the mark input in a mark reception screen is registered in the “mark character string” field by thereception unit 15 a. An ID of a group to which the mark identified by the ID registered in the “mark ID” field belongs or an ID of a group to which the mark indicated by the character string registered in the “mark character string” field belongs is registered in the “group ID” filed by thereception unit 15 a. - For example, a first record of the group-
mark DB 14 e illustrated in an example ofFIG. 7A indicates that the mark identified by ID “1002” belongs to a group identified by ID “1”. Further, the first record of the group-mark DB 14 e illustrated in an example ofFIG. 7B indicates that the mark identified by a character string “¥” belongs to a group identified by the ID “1”. - The
storage unit 14 may be a storage device including, for example, a semiconductor memory device such as a flash memory, or a hard disk or an optical disk. - The
control unit 15 includes an internal memory for storing a program in which various processing sequences are defined or a control data, and executes various processes by the program and the control data. As illustrated inFIG. 2 , thecontrol unit 15 includes thereception unit 15 a and thedisplay control unit 15 b. - When each opinion included in a group of opinions is disposed and displayed on a different area among display areas in the
display unit 12 or theelectronic blackboard 4 a, thereception unit 15 a receives registration of a mark by associating the mark with a plurality of opinions selected among the group of opinions. One aspect of thereception unit 15 a will be described. For example, when an instruction to execute a display control process is input from theinput unit 11 due to the manipulation of the touch pen or finger by the teacher, thereception unit 15 a generates an assignment selection screen and controls thedisplay unit 12 to display the assignment selection screen. - An example of an assignment selection screen generation method by the
reception unit 15 a will be described.FIG. 8 is a view explaining an example of an assignment selection screen generation method. When generating an assignment selection screen, thereception unit 15 a first acquires all of the IDs and the contents of the assignments registered in theassignment DB 14 b. Thereception unit 15 a, as illustrated in an example ofFIG. 8 , registers the acquired ID and the content of the assignments in the “assignment ID” field and the “assignment content” of theassignment selection screen 20 by associating the ID of the assignments with the contents of the assignments, respectively. Further, as illustrated in the example ofFIG. 8 , thereception unit 15 a prepares acheck box 20 a in a “selection button” field of theassignment selection screen 20 by associating thecheck box 20 a with the “assignment ID” field and the “assignment content” field. The teacher manipulates theinput unit 11 using the touch pen or finger to check thecheck box 20 a. For example, when thecheck box 20 a associated with a first record of theassignment selection screen 20 illustrated in the example ofFIG. 8 is checked, the checkedcheck box 20 a indicates the following matters. That is, thecheck box 20 a indicates that an assignment of which content is “How do you think about underage abortion?” is selected as the assignment identified by the ID “0001”. Further, as illustrated in an example ofFIG. 8 , thereception unit 15 a prepares abutton 20 b for acquiring the ID and the content of the assignment associated with the checked check box in theassignment selection screen 20. Further, thereception unit 15 a prepares abutton 20 c for closing theassignment selection screen 20 in theassignment selection screen 20. Further, thereception unit 15 a, as illustrated in the example ofFIG. 8 , prepares a message, which is used for urging the teacher to select the assignment, of “Please select an assignment intending for a student to review and depress ‘Transmission’ button.” in theassignment selection screen 20. Thereception unit 15 a generates theassignment selection screen 20 according to the method described above. Also, thereception unit 15 a controls thedisplay unit 12 to display theassignment selection screen 20. By doing this, thedisplay unit 12 displays theassignment selection screen 20. - The
reception unit 15 a determines whether the ID and the content of the assignment associated with the checkedcheck box 20 a are received after controlling thedisplay unit 12 to display theassignment selection screen 20. For example, thereception unit 15 a determines whether the ID and the content of the assignment associated with the checkedcheck box 20 a are acquired as a result of the depression of thebutton 20 b to determine whether the and the content of the assignment are received. - When the ID and the content of the assignment are received, the
reception unit 15 a transmits the received ID and the content of the assignment to thestudent terminal 3 through the network 5 using an IP address registered in thestudent DB 14 a. Then, as will be described below, a selection result of approval or disapproval about the transmitted content of the assignment, an opinion about the content of the assignment, and a student ID are transmitted from thestudent terminal 3 to theteacher terminal 2 through the network 5. By doing this, thereception unit 15 a may receive the opinion of the student or the selection result of approval or disapproval from thestudent terminal 3. Further, though not illustrated, the student ID may be input by the student at the time of logging-in the student terminal. - Also, the
reception unit 15 a acquires a limitation time associated with the received ID of the assignment from theassignment DB 14 b. Subsequently, thereception unit 15 a receives the selection result of approval or disapproval, the opinion about the content of the assignment, and the student ID from thestudent terminal 3 during a time period until the acquired limitation time elapses after transmitting the ID and the content of the assignment to thestudent terminal 3. When the selection result of approval or disapproval, the opinion about the content of the assignment, and the student ID are received, thereception unit 15 a performs the following process. That is, thereception unit 15 a specifies a table 14 c_1 in which the received ID of the assignment is registered in the “assignment ID” field among the plurality of tables 14 c_1 of theassignment reply DB 14 c. Thereception unit 15 a acquires the family name of the student associated with the student ID received from thestudent DB 14 a. Thereception unit 15 a adds a new record in the table 14 c_1, registers the acquired family name of student in the “student name” field, registers the received selection result of approval or disapproval in the “approval/disapproval” field and registers the received opinion in the “opinion content” field of the added record. - Also, the
reception unit 15 a registers each of the coordinates of upper left, lower left, upper right and lower right of the four corners of the area in which the opinion registered in the “opinion content” field is displayed in the “opinion display area coordinate” field of the added record. Further, thereception unit 15 a generates the coordinates of the four corners of the area in which the opinion registered is displayed such that the received plurality of opinions are displayed in a matrix shape, and registers the generated coordinates in the added record. - By performing the processes described above, the
reception unit 15 a registers the following data in the specified table 14 c_1 together with the selection result of approval or disapproval and the opinion about the content of the assignment received during a time period until the acquired limitation time elapses. That is, thereception unit 15 a registers the family name of student and the coordinates of the four corners of the area in which the opinion is displayed in the specified table 14 c_1 together with the selection result and the opinion. - When the limitation time elapses, the
reception unit 15 a controls theprojector 4 b to display the selection result of approval or disapproval, and the opinion on theelectronic blackboard 4 a in a matrix shape. Further, thereception unit 15 a controls thedisplay unit 12 to display the selection result of approval or disapproval and the opinion in a matrix shape. An example of process performed by thereception unit 15 a to control thedisplay unit 12 and theprojector 4 b to display the selection result of approval or disapproval and the opinion in a matrix shape will be described. For example, thereception unit 15 a acquires registered contents of the “student name” field, the “approval/disapproval” field, the “opinion content” field and the “opinion display area coordinate” field of all the records of the specified table 14 c_1. Also, thereception unit 15 a controls thedisplay unit 12 and theprojector 4 b to integrate and display the selection result registered in the “approval/disapproval” field, the content of the opinion registered in the “opinion content” field, and the family name registered in the “student name” field with respect to each of all the records. That is, thereception unit 15 a controls thedisplay unit 12 and theprojector 4 b to display the selection result, the content of the opinion, and the family name of student in the area specified by coordinates of the four corners registered in the “opinion display area coordinate” field. The processes described above are performed by thereception unit 15 a and thus, the selection result, the content of opinion and the family name of student are associated with one another and displayed in a matrix shape in thedisplay unit 12 and theelectronic blackboard 4 a.FIG. 9 is a view illustrating an example of displayed content when a selection result, a content of opinion and a family name of student are displayed on a display unit or an electronic blackboard in a matrix shape. For example, when the registered content of the “student name” field, the “approval/disapproval” field, the “opinion content” field and the “opinion display area coordinate” field of all the records of the table 14 c_1 as illustrated in the example ofFIG. 5 are acquired, thereception unit 15 a controls theprojector 4 b to display the content as indicated in the example ofFIG. 9 on theelectronic blackboard 4 a. Additionally, thereception unit 15 a controls thedisplay unit 12 to display the content as indicated in the example ofFIG. 9 . Here, each number of “40”, “80”, “120” and “160” arranged in a horizontal direction indicates that the X-coordinate from the origin of coordinate “0” in the example ofFIG. 9 . Further, each number of “30” and “60” arranged in a vertical direction indicates that the Y-coordinate from the origin of coordinate “0” in the example ofFIG. 9 . Further, thebutton 21 a is a button to end the display control process. - The example of
FIG. 9 represents a case where the selection result “disapproval” of the student “Tanaka” is displayed in an area specified by coordinates of the four corners (e.g., upper left coordinate (0, 60), lower left coordinate (0, 30), upper right coordinate (40, 60), lower right coordinate (40, 30)). Further, the example ofFIG. 9 represents a case where the opinion “i am worried about bringing up child when being unemployed because of the financial aspect.” of the student “Tanaka” is displayed in an area specified by coordinates of the four corners (e.g., upper left coordinate (0, 60), lower left coordinate (0, 30), upper right coordinate (40, 60), lower right coordinate (40, 30)). The same rule applies with opinions of other students. - Further, the
reception unit 15 a may transmit an instruction to display the selection result of approval or disapproval and the opinion that are received in a matrix shape to thestudent terminal 3. By doing this, the screen containing the content as illustrated in the example ofFIG. 9 is displayed. - When the opinions are displayed on the
display unit 12 or theelectronic blackboard 4 a in a matrix shape, thereception unit 15 a determines whether a mark input in handwriting by the manipulation of the electronic pen by the teacher exists on the opinions displayed on theelectronic blackboard 4 a. Further, thereception unit 15 a determines whether a mark input in handwriting by the manipulation of the touch pen or finger by the teacher exists based on the input result from theinput unit 11 which is the touch panel provided on thedisplay unit 12. - When it is determined that the mark input in handwriting exists, the
reception unit 15 a controls theprojector 4 b to display the mark input in handwriting on the opinions displayed on theelectronic blackboard 4 a in a matrix shape. Further, thereception unit 15 a controls thedisplay unit 12 to display the mark input in handwriting on the opinions displayed in a matrix shape. By the processes described above, the mark input in handwriting is displayed on the opinions displayed on theelectronic blackboard 4 a or thedisplay unit 12. -
FIG. 10 andFIG. 11 are views explaining examples of a mark input in handwriting. The example ofFIG. 10 indicates an example of the mark displayed on the opinions displayed in a matrix shape indicated in the example ofFIG. 9 . The example ofFIG. 10 indicates a case where amark 22 a having substantially a circular shape and associates a plurality of opinions replied by the students “Kuroda”, “Tanaka”, “Yamada” and “Honda” who describe their opinions from an economical point of view is input in handwriting. - Further, the example of
FIG. 11 indicates a case where amark 22 b is newly input in handwriting after themark 22 a having substantially the circular shape displayed on the opinion displayed in a matrix shape indicated in the example ofFIG. 10 is input in handwriting. Themark 22 b is a mark of a symbol “¥” indicating that the opinions associated by themark 22 a having substantially the circular shape are opinions described based on from the economical point of view. In the example ofFIG. 11 , theentire mark 22 b is included within an area surrounded by a line of themark 22 a having substantially the circular shape and associating the plurality of opinions replied by the students “Kuroda”, “Tanaka”, “Yamada” and “Honda”. In this case, themark 22 b belongs to the same group as a group to which themark 22 a belongs. - The
reception unit 15 a controls theprojector 4 b to display the mark input in handwriting on the opinions displayed on theelectronic blackboard 4 a and controls thedisplay unit 12 to display the mark input in handwriting on the opinions and then, performs the following process. That is, thereception unit 15 a acquires the coordinate of the start point and the coordinate of the end point of the mark input in handwriting every one stroke of a unicursal curve. Further, thereception unit 15 a acquires the coordinate of points between the start point and the end point of the mark along the mark at regular intervals. Further, thereception unit 15 a generates an ID of a new mark not registered in the coordinateDB 14 d. - Also, the
reception unit 15 a adds the new record in the coordinateDB 14 d and registers the generated ID of the mark in the “mark ID” field of the added record. Thereception unit 15 a registers the coordinate of the start point, the coordinates of the points between the start point and the end point and the coordinate of the end point of the mark input in handwriting in the “start point coordinate” field, the “progressed coordinate” field and the “end point coordinate” field of the added record, respectively. By doing this, the ID of mark, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are registered in the coordinateDB 14 d. - Subsequently, the
reception unit 15 a determines whether a new mark is surrounded by the line of the mark of which the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are registered in the coordinateDB 14 d before a new mark of which the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are newly registered in the coordinateDB 14 d. For example, thereception unit 15 a acquires the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point with respect to all the marks of which the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are registered in the coordinateDB 14 d before the new mark. Also, thereception unit 15 a determines whether the entire area of the new mark surrounded by the line connecting the coordinate of the start point, the progressed coordinates and the coordinate of the end point of the new mark is included within the area surrounded by the line connecting the coordinate of the start point, the progressed coordinates and the coordinate of the end point with respect to each of all the marks of which ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are acquired. By doing this, thereception unit 15 a may determine whether the new mark is surrounded by the line of each mark of which the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are registered in the coordinateDB 14 d before the new mark. - Here, when it is determined that a mark which includes the entire coordinate of the new mark within the area does not exist among the marks of which the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are registered in the coordinate
DB 14 d before the new mark, thereception unit 15 a determines whether the line of the new mark covers a plurality of areas in which the opinions are displayed. For example, when themark 22 a illustrated in an example ofFIG. 10 is input in handwriting, thereception unit 15 a determines that the line of thenew mark 22 a covers four areas, each of which displays the opinion of each of four students “Tanaka”, “Yamada”, “Honda” and “Kuroda”. - When it is determined that the line of the new mark covers the plurality of areas in which the opinions are displayed, the
reception unit 15 a specifies a record that the coordinates of four corners in the area are registered in the “opinion display area coordinate” field among all the records of the specified table 14 c_1 with respect to all the areas covered by the line of the new mark. Further, thereception unit 15 a specifies a record that the coordinates of four corners in the area are registered in the “opinion display area coordinate” field among all the records of the specified table 14 c_1 with respect to all the areas surrounded by the line of the new mark among the areas in which the opinions are displayed. - For example, in the example illustrated in
FIG. 10 , thereception unit 15 a specifies a first record that the coordinates of four corners of the area in which the opinion of the student “Tanaka” covered by the line of thenew mark 22 a is displayed are registered in the “opinion display area coordinate” field, among all the records of the specified table 14 c_1 illustrated in the example ofFIG. 5 . Further, thereception unit 15 a specifies a second record that the coordinates of four corners of the area in which the opinion of the student “Yamada” covered by the line of thenew mark 22 a is displayed are registered in the “opinion display area coordinate” field, among all the records of the specified table 14 c_1 illustrated in the example ofFIG. 5 . Further, thereception unit 15 a specifies a sixth record that the coordinates of four corners of the area in which the opinion of the student “Honda” covered by the line of thenew mark 22 a is displayed are registered in the “opinion display area coordinate” field, among all the records of the specified table 14 c_1 illustrated in the example ofFIG. 5 . Further, thereception unit 15 a specifies a fifth record that the coordinates of four corners of the area in which the opinion of the student “Kuroda” covered by the line of thenew mark 22 a is displayed are registered in the “opinion display area coordinate” field, among all the records of the specified table 14 c_1 illustrated in the example ofFIG. 5 . Accordingly, in the example illustratedFIG. 10 , thereception unit 15 a specifies four records corresponding to the first record, the second record, the fifth record and the sixth among all the records of the specified table 14 c_1 illustrated in the example ofFIG. 5 . - Also, the
reception unit 15 a generates an ID of a group which is not registered in the “group ID” fields of all the tables 14 c_1 of theassignment reply DB 14 c, and registers the generated ID of the group in the “group ID” fields of all the specified records. For example, thereception unit 15 a generates a group ID of “1” which is not registered in the “group ID” of all the tables 14 c_1, and registers the generated group ID of “1” in the “group ID” field of all the specified records, as illustrated in the example ofFIG. 5 . - Also, the
reception unit 15 a specifies a record that a new ID of a mark is registered in the “mark ID” field among all the records of the coordinateDB 14 d and registers the ID of the group which is newly generated in the “group ID” field of the specified record. For example, when the new ID of the mark is “1001” and the newly generated ID of the group is “1”, thereception unit 15 a performs the following process. That is, thereception unit 15 a registers the ID of the group “1” which is newly generated in the “group ID” field of the first record of the coordinateDB 14 d, as illustrated in the example ofFIG. 6 . - In the meantime, when it is determined that all the coordinates of the new mark are included within an area surrounded by a line connecting the coordinate of the start point, the progressed coordinates and the coordinate of the end point of any mark among all the marks of which the ID, the coordinate of the start point, the progressed coordinates and the coordinate of the end point are registered in the coordinate
DB 14 d before the new mark, thereception unit 15 a performs the following process. That is, thereception unit 15 a specifies a mark which includes all the coordinate of the new mark within the area surrounded by the line connecting the coordinate of the start point, the progressed coordinates and the coordinate of the end point. Also, thereception unit 15 a determines whether the ID of the group is registered in the coordinateDB 14 d by being associated with the specified ID of the mark. - Here, when it is determined that the ID of the group is not registered in the coordinate
DB 14 d by being associated with the specified ID of the mark, thereception unit 15 a performs the following process. That is, thereception unit 15 a performs the process described above which determines whether the line of the new mark covers the plurality of areas in which the opinions are displayed. Also, when it is determined that the line of the new mark covers the plurality of areas in which the opinions are displayed, thereception unit 15 a performs the process described above in which a record that the coordinates of four corners of the area are registered in “opinion display area coordinate” field with respect to all the areas covered by the line of the new mark is specified among all the records of the specified table 14 c_1. Further, thereception unit 15 a also performs the process described above in which a record that the coordinates of four corners of the area are registered in “opinion display area coordinate” field is specified among all the records of the specified table 14 c_1 similarly with respect to all the areas surrounded by the line of the new mark. Also, thereception unit 15 a performs the process described above which generates an ID of the group which is not registered in the “group ID” field of all the tables 14 c_1, and registers the generated ID of the group in the “group ID” field of all the specified records. Also, thereception unit 15 a performs the process described above which specifies a record that a new ID of a mark is registered in the “mark ID” field among all the records of the coordinateDB 14 d, and registers the ID of the group which is newly generated in the “group ID” field of the specified record. - In the meantime, when it is determined that the ID of the group is registered in the coordinate
DB 14 d by being associated with the specified ID of the mark, thereception unit 15 a specifies a record that the ID of the group registered in the coordinateDB 14 d by being associated with the specified ID of the mark is registered in the “group ID” field among all the records of the group-mark DB 14 e. Also, thereception unit 15 a registers the new ID of the mark in the “mark ID” field of the specified record. By doing this, thereception unit 15 a may associate the ID of the group registered in the coordinateDB 14 d by being associated with the specified ID of mark with the new ID of the mark to be registered in the group-mark DB 14 e. - For example, when the ID of the
new mark 22 b is “1002”, the ID of the specifiedmark 22 a is “1001” and the ID of the group registered in the coordinateDB 14 d by being associated with the ID of the mark “1001” is “1”, thereception unit 15 a associates the new ID of themark 22 b “1002” with the ID of the group “1” to be registered in the group-mark DB 14 e, as indicated in the first record of the group-mark DB 14 e illustrated in the example ofFIG. 7 . - Further, the
reception unit 15 a determines whether an instruction to execute a mark reception process is input due to the manipulation of the electronic pen by the teacher in any one area in which any one opinion among the opinions displayed in theelectronic blackboard 4 a in a matrix shape is displayed. Further, thereception unit 15 a determines whether an instruction to execute a mark reception process is input due to the manipulation of the touch pen or finger by the teacher in any one area in which any one opinion among the opinions displayed on thedisplay unit 12 in a matrix shape is displayed. - When it is determined that the instruction to execute the mark reception process is input, the
reception unit 15 a executes the mark reception process. - In the mark reception process, the
reception unit 15 a determines whether the ID of the group is registered in theassignment reply DB 14 c by being associated with a family name of a student who has replied the opinion displayed in the area in which the instruction to execute the mark reception process is input. For example, in the example illustrated inFIG. 10 , when the family name of the student is “Honda”, thereception unit 15 a determines whether the ID of the group is registered in theassignment reply DB 14 c by being associated with the family name of student “Honda”. - When it is determined that whether the ID of the group is registered in the
assignment reply DB 14 c by being associated with the family name of the student who has replied the opinion displayed in the area in which the instruction to execute the mark reception process is input, thereception unit 15 a controls theprojector 4 b to display a mark reception screen for receiving a mark on theelectronic blackboard 4 a. Further, thereception unit 15 a controls thedisplay unit 12 to display the mark reception screen. By doing this, the mark reception screen is displayed on theelectronic blackboard 4 a or thedisplay unit 12. The mark reception screen includes an area in which a character and a character string indicating the mark is input and a button (registration button) for registering the character or the character string indicating the mark input into the area in the group-mark DB 14 e. -

The mark reception screen includes a button (registration button) 23 b for registering an area 23 a in which a character and a character string indicating the mark is input and a button (registration button) 23 b for registering the character or the character string indicating the mark input into the area 23 a in the group-mark DB 14 e. - Also, the
reception unit 15 a determines whether the character or the character string indicating the mark is input, due to the manipulation of the electronic pen by the teacher, to the area described above of the mark reception screen displayed on theelectronic blackboard 4 a. Further, thereception unit 15 a determines whether the character or the character string indicating the mark is input, due to the manipulation of the touch pen or finger by the teacher, to the area described above of the mark reception screen displayed on thedisplay unit 12. - When it is determined that the character or the character string indicating the mark is input, the
reception unit 15 a controls theprojector 4 b to display the character or the character string indicating the input mark on the area of the mark reception screen displayed on theelectronic blackboard 4 a. Further, thereception unit 15 a controls thedisplay unit 12 to display the character or the character string indicating the input mark on the area of the mark reception screen. For example, when the character “ø” indicating the mark is input, thereception unit 15 a controls theprojector 4 b or thedisplay unit 12 to display the character “¥” indicating the mark is displayed on the area 23 a, as illustrated in an example ofFIG. 12 . - Also, the
reception unit 15 a determines whether the registration button of the mark reception screen displayed on theelectronic blackboard 4 a is depressed due to the manipulation of the electronic pen by the teacher. Further, thereception unit 15 a determines whether the registration button of the mark reception screen displayed on thedisplay unit 12 is depressed due to the manipulation of the touch pen or finger by the teacher. - When it is determined that the registration button is depressed, the
reception unit 15 a performs the following process. That is, thereception unit 15 a specifies the ID of the group registered in theassignment reply DB 14 c by being associated with a family name of student who has replied the opinion displayed on the area in which the instruction to execute the mark reception process is input. Also, thereception unit 15 a specifies a record that the specified ID of the group is registered in the “group ID” field among all the records of the group-mark DB 14 e. Also, thereception unit 15 a registers the character or the character string of the mark displayed on the area described above of the mark reception screen in the “mark character string” field of the specified record. By doing this, the specified ID of the group and the character or the character string of the mark on displayed on the area described above of the mark reception screen are associated with each other to be registered in the group-mark DB 14 e. For example, as indicated by the first record of the group-mark DB 14 e ofFIG. 7B , thereception unit 15 a associates the specified ID of the group “1” with the character “¥” of the mark displayed on the area 23 a of the mark reception screen 23 to be registered in the group-mark DB 14 e. - Also, the
reception unit 15 a closes the mark reception screen and ends the mark reception process. - Further, when it is determined that the ID of the group is not registered in the
assignment reply DB 14 c by being associated with a family name of student who has replied the opinion displayed on the area in which the instruction to execute the mark reception process, thereception unit 15 a controls theprojector 4 b to display an error screen indicating that the group is not set in relation to the student on theelectronic blackboard 4 a. Further, thereception unit 15 a controls thedisplay unit 12 to display the error screen. By doing this, the error screen is displayed on theelectronic blackboard 4 a or thedisplay unit 12. Anerror screen 24 includes a message indicating that the group is not set in relation to the student and a button for closing the error screen. -
FIG. 13 is a view illustrating an example of an error screen. Theerror screen 24 illustrated in an example ofFIG. 4 includes a message of “Please be informed that a group for the selected student is not set” and a button 24 a for closing theerror screen 24. Specifically, when an instruction to execute the mark reception process is input in an area of the student “Asai” displayed on the lower right portion ofFIG. 13 , the opinion of the “Asai” is not set in any group and thus, theerror screen 24 is displayed as illustrated inFIG. 13 . - Also, the
reception unit 15 a determines whether the button for closing the error screen displayed on theelectronic blackboard 4 a is depressed due to the manipulation of the electronic pen by the teacher. Further, thereception unit 15 a determines whether the button for closing the error screen displayed on thedisplay unit 12 is depressed due to the manipulation of the touch pen or finger by the teacher. - When it is determined that the button for closing the error screen is depressed, the
reception unit 15 a closes the error screen and ends the mark reception process. - Further, the
reception unit 15 a determines whether the button to end a display control process is depressed due to the manipulation of the electronic pen by the teacher when the opinions are displayed on theelectronic blackboard 4 a in a matrix shape. Further, thereception unit 15 a determines whether the button to end the display control process is depressed due to the manipulation of the touch pen or finger by the teacher when the opinions are display on thedisplay unit 12 in a matrix shape. - When it is determined that the button to end the display control process is depressed, the
reception unit 15 a ends the display control process. - Referring back to the description of
FIG. 2 , in a case where any one opinion included in the group of opinions is designated by the teacher, thedisplay control unit 15 b performs the following process when the designated opinion is included in a plurality of opinions selected from the group of opinions. That is, thedisplay control unit 15 b controls theprojector 4 b to display the mark registered by being associated with the plurality of selected opinions on theelectronic blackboard 4 a, together with the designated opinion. Further, thedisplay control unit 15 b controls thedisplay unit 12 to display the mark registered by being associated with the plurality of selected opinions, together with the designated opinion. - One aspect of the
display control unit 15 b will be described. For example, thedisplay control unit 15 b determines whether an opinion to be displayed in an enlarged scale is designated from the opinions displayed on theelectronic blackboard 4 a in a matrix shape using the electronic pen by the teacher. Further, thedisplay control unit 15 b determines whether an opinion to be displayed in an enlarged scale is designated from the opinions displayed on thedisplay unit 12 in a matrix shape using the touch or the finger by the teacher. - When it is determined that the opinion to be displayed in an enlarged scale is designated, the
display control unit 15 b executes an opinion display process. - In the opinion display process, the
display control unit 15 b determines whether the ID of the group is registered in theassignment reply DB 14 c by being associated with the content of the designated opinion. - When it is determined that the ID of the group is registered in the
assignment reply DB 14 c by being associated with the content of the designated opinion, thedisplay control unit 15 b determines whether any one of the ID of the mark and the character or character string of the mark is registered in the group-mark DB 14 e by being associated with the ID of the group determined as registered in theassignment reply DB 14 c. - When it is determined that any one the ID of the mark and the character or character string of the mark is registered in the group-
mark DB 14 e by being associated with the ID of the group determined as registered in theassignment reply DB 14 c, thedisplay control unit 15 b determines whether the ID of the mark exists among data determined as registered in the group-mark DB 14 e. - When it is determined that the ID of mark exists among the data determined as registered in the group-
mark DB 14 e, thedisplay control unit 15 b acquires the coordinate of the start point, the progressed coordinates and the coordinate of the end point associated with the ID of the mark from the coordinateDB 14 d with respect to each of all the IDs of the marks determined as registered in the group-mark DB 14 e.

For example, when an instruction to execute the display control process is input to thecontrol unit 15 from theinput unit 11, the display control process according to the embodiment is executed by thecontrol unit 15. - As illustrated in
FIG. 20A andFIG. 20B , thereception unit 15 a generates an assignment selection screen and controls thedisplay unit 12 to display the generated assignment selection screen (S101). - The
reception unit 15 a determines whether the ID and the content of the assignment associated with the checkedcheck box 20 a is received (S102). When it is determined that the ID and the content of the assignment are not received (“NO” at step S102), thereception unit 15 a performs the process of step S102 again. - In the meantime, when it is determined that the ID and the content of the assignment are received (“YES” at step S102), the
reception unit 15 a transmits the received ID and the content of the assignment to thestudent terminal 3 through the network 5 using an IP address registered in thestudent DB 14 a (S103). - Also, the
reception unit 15 a acquires the limitation time associated with the received ID of the assignment from theassignment DB 14 b (S104). Subsequently, thereception unit 15 a determines whether the selection result of approval or disapproval, the opinion about the content of the assignment, and the student ID are received from the student terminal 3 (S105). When it is determined that the selection result of approval or disapproval, the opinion about the content of the assignment, and the student ID are not received (“NO” at step S105), thereception unit 15 a proceeds to step S108 to be described below. In the meantime, when it is determined that the selection result of approval or disapproval, the opinion about the content of the assignment, and the student ID are received (“YES” at step S105), thereception unit 15 a specifies the table 14 c_1 in which the received ID of the assignment is registered in the “assignment ID” field among a plurality of the tables 14 c_1 of theassignment reply DB 14 c. Also, thereception unit 15 a adds a new record in the specified table 14 c_1 and acquires a family name of a student associated with the student ID from thestudent DB 14 a. Also, thereception unit 15 a registers the acquired family name of the student in the “student name” field of the added record, registers the selection result of approval or disapproval in the “approval/disapproval” field of the added record, and registers the received opinion in the “opinion content” field of the added record (S106). - Also, the
reception unit 15 a registers each of the coordinates of upper left, lower left, upper right, lower right of the four corners of the area in which the opinion registered in the “opinion content” field is displayed in the “opinion display area coordinate” field of the added record (S107). - The
reception unit 15 a determines whether a time after transmitting the ID and the content of the assignment to thestudent terminal 3 exceeds the limitation time (S108). When it is determined that the time does not exceed the limitation time (“NO” at step S108), thereception unit 15 a goes back to step S105. - In the meantime, when it is determined that the time exceeds the limitation time (“YES” at step S108), the
reception unit 15 a acquires the received selection results of approval or disapproval and the opinion from theassignment reply DB 14 c, and controls theprojector 4 b to display the acquired selection results of approval or disapproval and the opinion on theelectronic blackboard 4 a in a matrix shape. Further, thereception unit 15 a acquires the received selection results of approval or disapproval and the opinion from theassignment reply DB 14 c, and controls thedisplay unit 12 to display the acquired selection results of approval or disapproval and the opinion in a matrix shape. Further, thereception unit 15 a may transmit an instruction to display the received selection results of approval or disapproval and the opinion in a matrix shape to the student terminal 3 (S109). - The
reception unit 15 a determines whether a mark input in handwriting due to the manipulation of the electronic pen by the teacher exists on the opinion displayed on theelectronic blackboard 4 a. Further, thereception unit 15 a determines whether the mark input in handwriting due to the manipulation of the touch pen or finger by the teacher exists based on the input result from theinput unit 11 which is the touch panel provided on the display unit 12 (S110). As such, it is determined whether the mark input in handwriting exists in one of theelectronic blackboard 4 a and thedisplay unit 12. When it is determined that the mark input in handwriting does not exist (“NO” at step S110), thereception unit 15 a proceeds to step S121 to be described below. - In the meantime, when it is determined that the mark input in handwriting exists (“YES” at step S110), the
